Investigation of the effects of surface roughness and shot peening on the tooth root bending strength of case-carburized gears

D. Kratzer et al.

Summary: Previous studies have shown the positive effects of shot peening, superfinishing, and polish grinding on gear load-carrying capacity. However, the effects of superfinishing or polish grinding on tooth root bending strength have not been thoroughly investigated. This study conducted extensive experiments and found that while superfinishing and polish grinding do not significantly influence tooth root bending strength, the positive effects of shot peening are maintained when combined with these finishing processes.

Effect of layer orientation on the single tooth bending fatigue strength of polymer gears manufactured by selective laser sintering

A. Karthik Pandian et al.

Summary: This study examines the effect of tooth layer orientation on the bending fatigue behavior of Nylon 12 spur gears manufactured by selective laser sintering. It finds that the gears with a tooth configuration of 40 degrees have the highest strength, while those with a configuration of 160 degrees have the lowest strength. Compared to injection molded gears, selective laser sintering gears have lower bending fatigue life and higher surface temperature.

On the determination of the bending fatigue strength in and above the very high cycle fatigue regime of shot-peened gears

D. Fuchs et al.

Summary: To meet the demands of lightweight design goals and performance enhancement, shot-peening treatment can be applied to increase bending fatigue strength of gears in gearboxes. However, shot-peened gears may exhibit tooth root fracture damage at high load cycles, potentially leading to a further decrease in bending load carrying capacity.

Bending Fatigue Life Prediction Model of Carburized Gear Based on Microcosmic Fatigue Failure Mechanism

Hailong Deng et al.

Summary: The study found that cracks in carburized gears originate from stress concentration on the tooth surface. By considering surface residual stress, notch effect, stress gradient, and crack size, models for initiation life and growth life were established. The overall life prediction model was developed based on crack initiation and propagation behaviors, with prediction accuracy within three times of the test life.

Computational model for bending fatigue prediction of surface hardened spur gears based on the multilayer method

Ivan Cular et al.

Summary: This paper proposes a computational model for predicting both the location and the required number of cycles for bending fatigue failure in surface hardened spur gears. Linear elastic stresses and strains in a single tooth bending fatigue test are corrected for elastic-plastic material behavior. The tooth root region of spur gear is divided into layers, and fatigue properties are assigned to each layer via the hardness method. Based on the multiaxial fatigue criteria, fatigue failure location and corresponding fatigue lives are estimated. The predicted fatigue lives, failure locations, and transition from surface to subsurface fatigue failure show good agreement with the experimental results.

Effect of spatial hardness distribution in rolling contact fatigue performance of bearing contacts

Steven J. Lorenz et al.

Summary: This investigation examines the effect of various spatial hardness gradients on rolling contact fatigue life. The results show that polynomial gradients with degree greater than 1 outperform linear and polynomial gradients with degree less than 1, particularly at shallower gradient depths. Additionally, increasing gradient depth and increasing compressive residual stress improve the resistance to rolling contact fatigue.

An Experimental Evaluation of High-Cycle Gear Tooth Bending Fatigue Lives Under Fully Reversed and Fully Released Loading Conditions With Application to Planetary Gear Sets

Isaac J. Hong et al.

Summary: This experimental study compares high-cycle gear tooth bending fatigue lives of spur gears under fully reversed and fully released loading conditions. Statistical analysis reveals that gears under fully reversed loads have shorter bending lives compared to gears under fully released loads at the same maximum tooth root stress. Various kinematic conditions of planetary gear sets are considered to determine equivalent number of tooth loading cycles per revolution of the sun gear, in order to ensure that all gear components in a stress-balanced gear set have the same bending fatigue life.

A debris layer evolution-based model for predicting both fretting wear and fretting fatigue lifetime

Fei Shen et al.

Summary: A continuum damage mechanics (CDM) approach considering debris layer evolution is proposed for investigating fretting wear and fretting fatigue behavior of Ti-6Al-4V. An elastic-plastic-damage model is developed to calculate stress, strain, and fatigue damage fields. The effects of debris layer evolution on fretting fatigue lifetime, wear profile, contact pressure, and subsurface stress are evaluated for more accurate predictions.

Numerical model for bending fatigue life estimation of carburized spur gears with consideration of the adjacent tooth effect

Kresimir Vuckovic et al.

Summary: This paper proposes a computational model for predicting bending fatigue failure of case hardened spur gears, taking into account the effect of the adjacent tooth on bending fatigue lives. Through the model, it is found that bending fatigue lives can vary by approximately 22% when considering the adjacent tooth effect, which should be considered when estimating bending fatigue lives of spur gears.

A continuum damage mechanics finite element model for investigating effects of surface roughness on rolling contact fatigue

Steven J. Lorenz et al.

Summary: In this study, a CDM FE model was developed to investigate the effects of surface roughness on RCF life, using optical surface profilometer to measure roughness of deep groove bearings. The results showed that as roughness amplitude increases or lambda ratio decreases, fatigue lives decrease for various frequencies. Subsurface failure fatigue lives are reduced with increasing roughness frequency, regardless of amplitude or Hertzian pressure. The investigation results were used to develop surface roughness effects for RCF life equations in rolling element bearing applications.

Gear Root Bending Strength: A Comparison Between Single Tooth Bending Fatigue Tests and Meshing Gears

Luca Bonaiti et al.

Summary: Gear tooth breakage due to bending fatigue is a dangerous failure mode, and the precise definition of tooth bending strength is crucial in gear design. Single tooth bending fatigue tests are commonly used to study this failure mode, but when designing gear sets, the actual loading conditions and strength of meshing gears must be taken into consideration.

Bending Fatigue Behaviour and Fatigue Endurance Limit Prediction of 20Cr2Ni4A Gear Steel after the Ultrasonic Surface Rolling Process

Zhiyuan Wang et al.

Summary: The authors used ultrasonic surface rolling process (USRP) to strengthen 20Cr2Ni4A carburized gear steel, increasing the fatigue limit and analyzing the influence of surface properties and cross-section mechanical properties on fatigue life. The USRP process transformed the steel into a gradient material with five layers, and the coupling mechanism between the ultrasonic surface strengthening deformation layer and the carburized layer of 20Cr2Ni4A carburized gear steel was explained. The fatigue performance after USRP treatment was explained from the perspectives of the surface and cross section of the samples.
